Plugged it into an auto solver, there were no solutions. This puzzle is illogical so as he said, if you don't like illogical puzzles save yourself some time.
It depends how you define logical. It can be done using logic to work out where parts can't go not just where they can go, such as the 4 at the bottom.
R25c23 must be x because the "0" of column 22 If r25c22 is black (hypothesis) then r25c21, r25c20, r25c19 must be black (because the 4 in row 25) and then r24c20 must be x (because the 1 of column) r24c21 must be black (because the 3 of column)
impossible: got a 2 in row 24 so, hypothesis was wrong. Conclusion: r25c22 is x
This is logic. You can't define logic otherwise. Is easier to see that using temporaries, but is not necessary.
Sorry, Tsir, but if that's the case, then the aliens have superior logic to our own. All of Serbanqq's puzzles are logical, but some of them require more focus, more thinking about how to solve them. That doesn't make them illogical. It just means some people don't have the patience to solve them. This particular one is very challenging, and requires more extensive use of temporaries - some may call that illogical, but the majority of his puzzles can be solved "logically" by the most basic definition. For a site that focuses on using logic, it's surprising how many people have no interest in expanding their way of thinking. Those aliens could teach us a lot, if we would only listen. ;)
Whew! That was fun! Challenging, but solvable without having to make random guesses. Those little beasts bug me a lot during the summer; can't golf in peace without a bunch of them pestering me. Thank you for another fabulous puzzle Serbanqq!
Wao...if you enjoy a challenge, this is it!!! THis should be "the Mother Of All Hanjies". By the way, this Hanjie is 100% logical, no temps necessary, if you have the patience (as Elise said..). Thnaks very much Serbanqq...curious to know what Serbanqq consider to be his most difficult Hanjie...
@Serif: The 4 in Row 25 can be found logically. Next, find the 6, the 8, the 9... :)
If r25c22 is black (hypothesis)
then r25c21, r25c20, r25c19 must be black (because the 4 in row 25)
and then
r24c20 must be x (because the 1 of column)
r24c21 must be black (because the 3 of column)
impossible: got a 2 in row 24
so, hypothesis was wrong. Conclusion: r25c22 is x
This is logic. You can't define logic otherwise.

If you can't work this one out, instead of complaining, train your brain on some easier Hanjie and come back later and try it again.
It's a superb puzzle; perhaps one of the best ones on the site.
Aucun pif, que du cerveau en train de travailler...
